A two-dimensional model for simulation of gas discharges along a resin insulator in SF 6 /N 2 gas mixtures is developed by means of the Particle-in-cell and Monte Carlo (PIC-MCC) approach. The electron swarm and the following streamer developments are fully simulated, in which the elastic, exciting, ionising and attaching collisions between electrons and neutral gas molecules are.

    From to late s, this group developed a variety of numerical methods to simulate transient two-dimensional fluid flows, such as Particle-in-cell method (Harlow, ), Fluid-in-cell method (Gentry, Martin and Daly, ), Vorticity stream function method (Jake Fromm, ), and Marker-and-cell method (Harlow and Welch, ). We perform two- dimensional, particle-in-cell simulations of this instability. We observe an initial growth of circularly polarized nonpropagating magnetic waves as predicted in linear theory. It is demonstrated that in some cases the magnetic energy density in the growing waves can .

The particle-in-cell (PIC) method refers to a technique used to solve a certain class of partial differential this method, individual particles (or fluid elements) in a Lagrangian frame are tracked in continuous phase space, whereas moments of the distribution such as densities and currents are computed simultaneously on Eulerian (stationary) mesh points.

The company was founded in by Dr. Lubos Brieda. The name of the company is taken from the Particle In Cell Method commonly. Ion noise in output signal in klystron was obtained by particle in cell method.

The phase fluctuation in output signal is caused by the change of the beam current DC velocity which is affected by the change of the ion amount. The phase of output signal changed with the change of beam electron amount. A particle‐in‐cell (PIC) simulation of an axisymmetric electron‐cyclotron‐resonance (ECR) etching tool is developed in which up to 2×10 6 particles per species are loaded in a two‐dimensional spatial computational mesh (r,z), along with three velocity components (v r,v θ,v z).An ECR heating scheme based on single‐particle trajectories in the resonance zone generates the simulated.

The current tool of choice for modeling these interactions is the particle-in-cell (PIC) method. In strong fields, the motion of charged particles and their spin are effected by RR.

The Particle in Cell (PIC) method is a particle-mesh technique that eciently allows such description. Still, realistic plasma simulations re-quire huge data sets and are computationally expensive. The work of coding this method is simplified by using Particle-In-Cell and parallelization methods already developed for PIC plasma simulations to follow the classical paths.

This method was originally developed by Dean Dauger in a one-dimensional parallel Quantum PIC code. We are currently extending this method into a two-dimensional parallel. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid ers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces defined by boundary conditions.
